How do I install VST plug-ins?First, download and unzip the VST Enabler.

Place the unzipped VST Enabler, along with your VST plug-ins, into the “Plug-ins” folder in the Audacity installation folder. (On Mac OS X, this is usually in the Applications folder. On Windows, it is usually under Program Files.)

The next time you start Audacity, your VST effects will appear at the bottom of the “Effect” menu.
